The concept is great. However the straws are too big in diameter for the person I bought them for to be able to use them. Having options of sizes or a valve that could be inserted into a narrower straw would be beneficial.
Straws with a discreet, built-in valve that makes drinking easier, sold in a pack of 10|||ARK's One-Way Straws make drinking easier for individuals with a weak suck, oral motor difficulties, and/or problems generating and maintaining suction. Each straw features a built-in valve that controls the direction of fluid one-way - fluid flows up into the straw, but does not empty back into the cup. With fluid remaining at the top of the straw, less air is ingested and less effort is required to drink. Users therefore tend to experience less coughing and choking while consuming more fluids. Because the valves are built-in, these straws provide both convenience for the caregiver and discretion for the user. They save time and labor for the caregiver/therapist while increasing independence, dignity, and hydration for the individual.
